Abstract: 516,229. Power hammers. BURGESS, A. F. (Menck & Hambrock Ges.). June 15, 1938, No. 17792. [Class 83 (iv)] In compression ignition pile drivers with a stationary cylinder in which descent is accelerated by compressed air above the ram for starting, the cylinder and ram are both lifted and allowed to fall until the cylinder engages the pile whereupon the ram is released to continue its movement. A spring-pressed pivoted hook 10, Fig. 1, carried by a lifting rod 2 is splined for a key 15, which prevents rotation of. the rod. The hook has a toothed part 10a engaging a second hook 3 fixed to a pivot 7, to which is also attached a spring pressed lever 8, having an attached rope 14. When starting, a lifting rope 16 is attached to the rod 2 and the rope 14 pulled downwardly to rotate the hook 3 and free the .hook -10. A ram 13, which is at its .lower position is engaged by lowering the rod 2 until the hook 10 engages a recess in the ram, whereupon the ram is raised by the rope 16 and rod 2. When the ram reaches its upper position, the hooks 3, 10 are engaged and the cylinder and ram lifted. When the rope 16 is slackened the rod 2 drops slightly as shown, and the hook 10 has rotated, the hook 10 is released from the ram. In a modification a spring pressed latch enters a recess in a sleeve carrying the hook for engaging the ram to maintain the ram in position. In another form the ram is engaged by levers 10c, Fig. 6 in a cage having projections 28 that are supported by releasing levers 26. A wedge-end 21 is connected by a chain 37 to a drum 25 on a shaft 41 having pinions at its ends engaged by racks 43 on a frame carrying a loose pulley for a lifting rope. The lifting rope may, however, be attached directly to the chain 37. On lifting, the chain is tightened and spreads the levers 10c against the tapered shoulder 32 in the ram by the action of the inclined surfaces 29 on the wedge end.

Title: A separation process
IPC: C10G25/03
Filed: 1966-04-25
Abstract: Naphthenes and/or cycloolefins are selectively adsorbed from mixtures also containing normal and/or iso-paraffins by means of a strontium type X molecular sieve.  The mixture to be treated may particularly be a jet fuel or kerosene, the adsorption being carried out at 700-800 DEG  F. either in the liquid phase under super-atmospheric pressure or, preferably, in the vapour phase at atmospheric pressure; subatmospheric pressures are alternatively used. The process is particularly effective in removing 2 and 3 ring naphthenes and/or olefins and alkyl derivatives thereof; specified naphthenes which may be removed include cyclohexane, decalin, perhydroanthracene, and perhydroanthrene. Desorption of the sieve may be effected by lowering the total pressure, raising the temperature, purging with an inert gas, or, preferably, displacement with a preferentially-adsorbed gas; suitable displacing agents are listed, those preferred being formulated <FORM:1113899/C4-C5/1> where R1, R2, R3 are H or C1-C5 alkyl.  Ammonia is preferred.  Adsorption and desorption may be effected simultaneously by inclusion of a displacing agent in the feed stream.  In one embodiment a jet fuel can be catalytically reformed to convert 1 and 2-ring naphthenes to benzene and condensed ring aromatics, and the unchanged 3-ring naphthenes can then be adsorbed by the strontium sieve.ALSO:Naphthenes and/or cycloolefines are selectively adsorbed from mixtures also containing normal and/or iso-paraffins by means of a strontium type X molecular sieve.  The mixture for treatment may be a jet fuel or kerosene and may be treated in the vapour phase at 15-50 p.s.i.a. and 70-800 DEG F.

Title: Improvements in modulating arrangements for carrier wave telephone or like systems
Inventor: HARRISON KENNETH WHITELEY
IPC: H04J1/04
Filed: 1953-06-30
Abstract: 783,509. Carrier transmission. TELEPHONE MANUFACTURING CO., Ltd. June 15, 1954 [June 30, 1953], No. 18142/53. Class 40 (4). In a two-way multi-channel carrier system using frequency frogging, i.e. two frequency bands f<SP>1</SP>, f<SP>2</SP> are used alternatively in each direction, as indicated in Fig. 1, with transposition at successive repeaters, regenerative modulation is employed so that cumulative errors in frequency translation are kept to a minimum. The oscillations applied to group modulators W1, W2, Fig. 5, are derived from a pilot current (80 kc/s.) which is filtered out at F10 and combined in modulator W3 with the frequency transposed pilot output of 48 kc/s. selected by filter F9. The desired output from modulator W3 is quadrupled to produce a stable group modulator frequency of 128 kc/s. whereby the input band of 68-116 kc/s. is changed to 12-60 kc/s. A repeater, Fig. 4 (Comp.), which is suitable for an adjacent repeater, wherein the frequency of the input pilot is lower than that of the output, includes a multiplier M1 between filter F9 and modulator W3, and in alternative embodiments, Figs. 6, 6B (Comp.), (not shown), a further multiplier is included in the path of the output pilot current. Alternative pilot frequencies are suggested and a system in which regenerative modulation is employed only at alternate stations is also described. In this latter system the group modulation frequency at the other stations is derived by multiplication of the incoming pilot. Choice of pilot frequencies for different channel grouping and spacing is discussed, and the use of the pilot for automatic voltage control is suggested. Control of a local oscillator by a frequency derived by regenerative modulation is also referred to.

Title: A new or improved device for mechanically determining information concerned with tides
IPC: G06G1/00
Filed: 1943-11-04
Abstract: 574,743. Tide rules. PARSONS, C. D. H. Nov. 4, 1943, No. 18284. [Class 106 (i)] A tide rule comprises two adjustable time scales, a date strip and a tide strip, said date and tide strips being adjustable in relation to one another and to the said time scales. The time scales are marked on two slides 38, 39 mounted in an oblong casing 1, Figs. 1 and 2, divided into two compartments 9, 24 by a central transverse partition 7. A tide strip 23 divided into sections on each of which the state of the tide for a certain port over a period of approximately 13 hours is shown in diagrammatic form is carried by two rollers 10, 11 in the compartment 9. By manipulation of the knobs 16, 17, the tide strip 23 can be wound from the roller 10 on to the roller 11 or vice versa and so any section can be brought on to a central supporting table 8 into the space between the slides 38, 39. In the compartment 24 a date strip 35 divided into sections having indices for 14 days is carried by rollers 25, 26 as shown in Fig. 2. The sections of this date strip can be brought into the gap between the slides 38, 39 on to the central supporting table 8 in a similar manner to the sections of the tide strip 23. The rollers 10, 11 and 25, 26 are provided with spring brakes so that the strips 23, 35 can be held in the desired positions. In an example of the tide rule in use, shown in Fig. 1, it is desired to find full information regarding tides at Dover and Folkestone on 5th February of the year for which the instrument is constructed, so the date strip rollers are turned until that section, which includes the 5th of February, appears between the time scale slides 38 and 39. The tide strip is then turned to bring the Dover and Folkestone section thereof into position between the time scales and the time scale slides are slid until the G.M.T. index on the slide 38 is against the index for Feb. 4/5 and the G.M.T. index on the slide 39 is against the index for Feb. 5/6. The clock time readings on the scales 38, 39 taken against the tide scale give the required information.
